[origin: EP2823973A1] The pneumatic tire 1A has a plurality of circumferential main grooves 21, 22 extending in the tire circumferential direction, a plurality of lug grooves 41 extending in the tire width direction, and a plurality of blocks 311 partitioned by the circumferential main grooves 21, 22 and the lug grooves 41 (see FIG. 2 and FIG. 3 ). Also, the block 311 has a bent groove 5a (5b) having a bent shape that is convex in one direction and that extends in the tire circumferential direction dividing the block 311 into two in the tire width direction. Also, the blocks 311, 311 that are adjacent to each other in the tire circumferential direction are disposed such that the bend directions of the bent grooves 5a, 5b are alternately reversed.
